IIRC there are two different diameters of Oakie bushings. The earlier ones also have a pin that keeps them in. The pin has to be removed to get it loose. I think they changed in around 1950 or 1951 that don't have the pin, but are just press fit. My 1950 was without the pin. I tried making a removal tool, but failed miserably and had to use a "rental" one from one of the vendors. The filling station lists 3 separate oakie bushings, 37-39, 40-50, and 51-54.
